Item validity of the physical demands from the Dictionary of Occupational Titles for the functional capacity evaluation of clients with chronic back pain

This study assessed the item validity of 15 of the physical demands from the Dictionary of Occupational Titles (DOT), as evaluated in a new approach to functional capacity evaluation (FCE) for clients with chronic back pain, the Gibson Approach to FCE (GAPP FCE). Fifty-two occupational therapists were sent the specifications of the items in the GAPP FCE procedures and were asked to rate the items in terms of item-objective congruence, relevance and difficulty. A response rate of 59.2% was obtained. The majority of the therapists agreed that most of the items were congruent with the objectives based on the definition of the physical demands from the DOT. The items evaluating Balancing and Pushing and Pulling had the lowest item-objective congruence. The evaluation of Balancing and the Lifting, Carrying and Pushing and Pulling of loads greater than light-medium weight (10–16 kg) were not considered significantly relevant. Concerns were raised about the difficulty and safety of the evaluation of Lifting, Carrying and Pushing and Pulling with clients with chronic back pain, particularly if the therapist evaluates the manual handling of medium to heavy loads. These results may have implications for other FCEs, particularly those which are based on the DOT, or when assessing clients with chronic back pain.

Interactions between physical and psychosocial demands of work associated to low back pain

OBJECTIVE: To examine the interaction between physical and psychosocial demands of work associated to low back pain. METHODS: Cross-sectional study carried out in a stratified proportional random sample of 577 plastic industry workers in the metropolitan area of the city of Salvador, Northeast Brazil in 2002. An anonymous standard questionnaire was administered in the workplace by trained interviewers. Physical demands at work were self-rated on a 6-point numeric scale, with anchors at each end of the scale. Factor analysis was carried out on 11 physical demand variables to identify underlying factors. Psychosocial work demands were measured by demand, control and social support questions. Multivariate analysis was performed using the likelihood ratio test. RESULTS: The factor analysis identified two physical work demand factors: material handling (factor 1) and repetitiveness (factor 2). The multiple logistic regression analysis showed that factor 1 was positively associated with low back pain (OR=2.35, 95% CI 1.50;3.66). No interaction was found between physical and psychosocial work demands but both were independently associated to low back pain. CONCLUSIONS: The study found independent effects of physical and psychosocial work demands on low back pain prevalence and emphasizes the importance of physical demands especially of material handling involving trunk bending forward and trunk rotation regardless of age, gender, and body fitness.

Facts about Iowa Law Enforcement Physical Standards for Pre-employment Testing, 2011

The Iowa Law Enforcement Academy Council, in recognizing the importance of physical fitness status for job performance, established this physical test regimen as a employment standard effective February 15, 1993. No person can be selected or appointed as a law enforcement officer without first successfully passing all of the elements of this test. (See 501 IAC 2.1, adopted pursuant to Section 80B.11(5), Code of Iowa.) Upon entry into the Academy every candidate will be given the same test as an assessment for training purposes and to ensure that each recruit can undergo the physical demands of the Academy without undue risk of injury, and with a level of fatigue tolerance to meet all Academy requirements. If at the time of entrance into the Academy an officer does not meet minimum standards, he or she will not be admitted. This pamphlet will provide information on the rationale, purpose, testing procedures, standards of performance and fitness activities to prepare for the fitness testing. It is intended to answer the basic questions pertaining to all aspects of the fitness testing process.

Physical fitness of industrial firefighters

Firefighting is widely known to be one of the most physically demanding civilian occupations. A subset of this is Industrial Firefighting, which places similarly high physical demands on Industrial Firefighters. Although there are some studies on community firefighters, literature is scant on Industrial Firefighters and their physical fitness. ^ A cross-sectional study of Industrial Firefighters in Petrochemical companies in Texas was carried out in 1996–98 to assess their physical fitness and to develop a set of physical agility criteria useful in their selection and ongoing fitness for duty evaluations. ^ A physical agility criteria and a fitness scorecard was developed based on seven parameters (resting heart rate, diastolic blood pressure, aerobic capacity, muscle strength, muscle endurance, trunk flexibility and total body fat) of musculoskeletal and cardiorespiratory fitness. Each indicator received a minimum of 0 to a maximum of 20 points, based on individual performance. Therefore a minimum and maximum achievable score for the entire battery of tests was 0 and 140 respectively. Of the 111 study subjects, 5 (4.5%) were far above average, 31 (28%) above average, 46 (41.5 %) average, 29 (26%) below average and 0 (0%) far below average as deemed by the physical fitness scorecard. The mean score was 77 (±23) with a minimum and maximum score of 35 and 135 respectively. ^ Following univariate analysis an exploratory factor analysis to group variables and to assess the overall role of constituent variables in total fitness of a firefighter was developed. This was followed by a stepwise linear regression analysis using aerobic capacity as a dependent variable. ^ Finally, a graded implementation strategy was devised, such that all existing Industrial Firefighters would have an opportunity to improve or maintain their physical fitness at or above average level as deemed by the fitness scorecard. ^

A comparison of the physiological demands of rugby union match-play when determined by absolute (ABS) or individual (IND) velocity bands in Global Positioning System (GPS) analysis

Since turning professional in 1995 there have been considerable advances in the research on the demands of rugby union, largely using Global Positioning System (GPS) analysis over the last 10 years. A systematic review on the use of GPS, particularly the setting of absolute (ABS) and individual (IND) velocity bands in field based, intermittent, high-intensity (HI) team sports was undertaken. From 3669 records identified, 38 studies were included for qualitative analysis. Little agreement on the definition of movement intensities within team sports was found, only three papers, all on rugby union, had used IND bands, with only one comparing ABS and IND methods. Thus, the aim of this study was to determine if there is a difference in the demands within positions when comparing ABS and IND methods for GPS analysis and if these differences are significantly different between the forward and back positional groups. A total of 214 data files were recorded from 26 players in 17 matches of the 2015/2016 Scottish BT Premiership. ABS velocity zones 1-7 were set at 1) 0-6, 2) 6.1-11, 3) 11.1-15, 4) 15.1-18, 5) 18.1-21, 6) 21.1-15 and 7) 25.1-40km.h-1 while IND zones 1-7 were 1) <20, 2) 20-40, 3) 40-50, 4) 50-70, 5) 70-80, 6) 80-95 and 7) 95-100% of player’s individually determined maximum velocity (Vmax). A 40m sprint test measured Vmax using OptaPro S4 10 Hz (catapult, Australia) GPS units to derive IND bands. The same GPS units were worn during matches. GPS outputs analysed were % distance, % time, high intensity efforts (HIEs) over 18.1 km.h-1 / 70% max velocity and repeated high intensity efforts (RHIEs) which consists of three HIEs in 21secs. General linear model (GLM) analysis identified a significant difference in the measurement of % total distance covered, between the ABS and IND methods in all zones for forwards (p<0.05) and backs (p<0.05). This difference was also significant between forwards and backs in zones 1, shown as mean difference ± standard deviation (3.7±0.7%), 6 (1.2±0.4%) and 7 (1.0±0.0%) respectively (p<0.05). Percentage time estimations were significantly different between ABS and IND analysis within forwards in zones 1 (1.7±1.7%), 2 (-2.9±1.3%), 3 (1.9±0.8%), 4 (-1.4±0.8%) and 5 (0.2±0.4%), and within backs in zones 1 (-10±1.5%), 2 (-1.2±1.1%), 3 (1.8±0.9%) and 5 (0.6±0.5%) (p<0.05). The difference between groups was significant in zones 1, 2, 4 and 5 (p<0.05). The number of HIEs was significantly different between forwards and backs in zones 6 (6±2) and 7 (3±2). RHIEs were significantly different between ABS and IND for forwards (1±2, p<0.05) although not between groups. Until more research on the differences in ABS and IND methods is carried out, then neither can be deemed a criterion method. In conclusion, there are significant differences between the ABS and IND methods of GPS analysis of the physical demands of rugby union, which must be considered when used to inform training load and recovery to improve performance and reduce injuries.

Heart rate, blood lactate and kinematic data of elite colts (under-19) rugby union players during competition

Physiological and kinematic data were collected from elite under-19 rugby union players to provide a greater understanding of the physical demands of rugby union. Heart rate, blood lactate and time-motion analysis data were collected from 24 players (mean +/- s((x) over bar): body mass 88.7 +/- 9.9 kg, height 185 +/- 7 cm, age 18.4 +/- 0.5 years) during six competitive premiership fixtures. Six players were chosen at random from each of four groups: props and locks, back row forwards, inside backs, outside backs. Heart rate records were classified based on percent time spent in four zones (>95%, 85-95%, 75-84%, <75% HRmax). Blood lactate concentration was measured periodically throughout each match, with movements being classified as standing, walking, jogging, cruising, sprinting, utility, rucking/mauling and scrummaging. The heart rate data indicated that props and locks (58.4%) and back row forwards (56.2%) spent significantly more time in high exertion (85-95% HRmax) than inside backs (40.5%) and outside backs (33.9%) (P < 0.001). Inside backs (36.5%) and outside backs (38.5%) spent significantly more time in moderate exertion (75-84% HRmax) than props and locks (22.6%) and back row forwards (19.8%) (P < 0.05). Outside backs (20.1%) spent significantly more time in low exertion (< 75% HRmax) than props and locks (5.8%) and back row forwards (5.6%) (P < 0.05). Mean blood lactate concentration did not differ significantly between groups (range: 4.67 mmol.l(-1) for outside backs to 7.22 mmol.l(-1) for back row forwards; P < 0.05). The motion analysis data indicated that outside backs (5750 m) covered a significantly greater total distance than either props and locks or back row forwards (4400 and 4080 m, respectively; P < 0.05). Inside backs and outside backs covered significantly greater distances walking (1740 and 1780 m, respectively; P < 0.001), in utility movements (417 and 475 m, respectively; P < 0.001) and sprinting (208 and 340 m, respectively; P < 0.001) than either props and locks or back row forwards (walking: 1000 and 991 m; utility movements: 106 and 154 m; sprinting: 72 and 94 m, respectively). Outside backs covered a significantly greater distance sprinting than inside backs (208 and 340 m, respectively; P < 0.001). Forwards maintained a higher level of exertion than backs, due to more constant motion and a large involvement in static high-intensity activities. A mean blood lactate concentration of 4.8-7.2 mmol.l(-1) indicated a need for 'lactate tolerance' training to improve hydrogen ion buffering and facilitate removal following high-intensity efforts. Furthermore, the large distances (4.2-5.6 km) covered during, and intermittent nature of, match-play indicated a need for sound aerobic conditioning in all groups (particularly backs) to minimize fatigue and facilitate recovery between high-intensity efforts.

O impacto dos factores humanos na segurança em cuidados de saúde : contribuição para uma revisão da literatura

RESUMO - A segurança dos doentes é, actualmente, um princípio fundamental dos cuidados de saúde. Apesar desta realidade, cada ponto no processo de prestação de cuidados contém um certo grau de insegurança inerente. Os eventos adversos podem resultar de problemas na prática, produtos, processos ou sistemas. A melhoria da segurança do doente implica um esforço de todo um sistema complexo, envolvendo uma ampla gama de acções de melhoria do desempenho, segurança e gestão ambiental de risco, incluindo, entre outras prioridades, a prática de cuidados de saúde em ambiente seguro e com a melhor qualidade. É sabido que todos os anos morrem nos hospitais portugueses, cerca de três mil pessoas, devido a erros cometidos pelos profissionais de saúde. Compreender o erro humano e intervir de forma adequada nas suas causas, implica, muito mais que uma avaliação do facto em si, mas uma avaliação de toda a estrutura onde é passível de ocorrer um erro. São inúmeros os factores que estão relacionados com esta temática, sendo os factores humanos, aqueles que poderão merecer alguma reflexão, pois são ainda algo omitidos nas orientações de gestão e nas considerações de chefias. Assim sendo, pretende-se que, com este projecto de investigação, através de uma revisão da literatura, sejam identificados os vários factores humanos que influenciam o desempenho dos profissionais de saúde, envolvidos na prestação directa de cuidados. Estes factores reflectem-se na segurança dos cuidados de saúde e na melhoria da qualidade prestados nas instituições de saúde. Face aos resultados conclusivos após a revisão de literatura, é verificado que os factores humanos que influenciam o desempenho dos profissionais de saúde são: comunicação e partilha de informação; conhecimento e formação; liderança; trabalho em equipa; cultura de segurança e aprendizagem; carga de trabalho; exigências físicas e ambiente de trabalho. É esperado que o contributo deste trabalho promova o conhecimento em torno desta temática e que se apresente como o início de uma aposta na valorização, cada vez mais importante, mas ainda limitada, destes valores intangíveis da gestão – os factores humanos. ----------------------------------- ABSTRACT - Patient safety is, nowadays, a fundamental principle of health care. Despite this fact, each point in the process of care contains an inherent degree of uncertainty. Adverse events may result from problems in practice, products, processes or systems. Improving patient safety requires an effort of a whole complex system, involving a wide range of measures to improve performance, safety and environmental risk management, including, among other priorities, the practice of health care in a safe environment and the best quality. It is known that every year die, in Portuguese hospitals, around three thousand people, due to mistakes made by health professionals. To understand human error and intervene as appropriate in their causes, it is required much more than an assessment of the fact itself, but an assessment of the whole structure where it is likely to occur. There are countless factors that are related to this issue, but human factors, those who may deserve some consideration, are still left out in management guidelines and supervisors considerations. Therefore, this research project seeks to determine, through a literature review, the identification of various human factors that influence the performance of healthcare providers involved in direct provision of care. The aim is also to know which factors are reflected in safety healthcare and how they are, in fact, crucial in the performance of professionals and in the promotion of quality and safety of the healthcare provided in healthcare institutions. Given the conclusive results after a review of literature, it is found that the human factors that influence the performance of health professionals are: communicating and sharing information, knowledge and training, leadership, teamwork, safety culture and learning; workload, physical demands and work environment. It is expected that this project may contribute to advance of the knowledge regarding this problem and be an essential tool to the beginning of a reliance on the development, increasingly important but still limited, of these intangibles management values – the human factors.

La détresse psychologique et les problèmes cardiovasculaires chez les travailleurs: une étude transversale de la comorbidité

L’objectif principal de ce mémoire consiste à déterminer s’il existe une association entre la détresse psychologique et les problèmes cardiovasculaires chez les travailleurs, suite à l’influence de certains facteurs professionnels. Les données proviennent de l’Enquête sur la santé dans les communautés canadiennes (cycle 3.1 de l’ESCC), menée par Statistique Canada en 2005. Notre échantillon est composé de 15 394 canadiens et canadiennes en emploi de 15 ans et plus, représentatif sur le plan de l’âge, du genre et de la distribution géographique du lieu de résidence. Les analyses de régressions logistiques montrent que quatre facteurs professionnels présentent une association significative avec la détresse psychologique : les demandes psychologiques, la menace de perdre son emploi, le soutien social au travail, la satisfaction au travail. Puis, trois facteurs s’avèrent être reliés au développement de problèmes cardiovasculaires, soit l’utilisation des compétences, la satisfaction au travail ainsi que le nombre d’heures travaillées. Les analyses de variances multiples (MANOVA) révèlent que la détresse psychologique est associée aux problèmes cardiovasculaires et que ces deux problèmes de santé peuvent se retrouver en situation de comorbidité. Selon les résultats, on observe que cinq facteurs sont significativement corrélés à la présence de détresse psychologique en même qu’un problème cardiovasculaire : les demandes psychologiques, la menace de perdre son emploi, le soutien social au travail, la satisfaction au travail ainsi que le nombre d’heures travaillées. Par ailleurs, l’utilisation des compétences, l’autonomie décisionnelle et les exigences physiques de travail ne sont pas significativement associés à la détresse psychologique et à la présence de problèmes cardiovasculaires.

Conditions de l’organisation du travail, consommation d’alcool à risque et médicaments psychotropes : le rôle modérateur des traits de personnalité

L'objectif principal de ce mémoire est d'évaluer le rôle modérateur de trois traits de personnalité, soit l'estime de soi, le sentiment de cohésion, ainsi que le centre de contrôle interne sur la relation entre les conditions de l'organisation du travail et la consommation d'alcool à risque, ainsi que la consommation de médicaments psychotropes des travailleurs canadiens. Les données sur lesquelles nous nous sommes basés proviennent de l'Enquête Nationale sur la Santé de la Population (ENSP) de Statistique Canada. Celle-ci a été conduite à des intervalles de deux ans, de l’année 1994 jusqu'à l’année 2003, et comprend ainsi cinq cycles longitudinaux. Les analyses multiniveaux que nous avons effectuées nous ont permises d’identifier cinq variables des conditions de l'organisation du travail qui s’associent de manière significative à la consommation d'alcool à risque, soit l’utilisation des compétences qui augmente de 7% le risque de faire partie du groupe de consommation d’alcool à risque par un travailleur, les demandes psychologiques qui augmentent ce risque de 69%, et les travailleurs confrontés à un horaire de travail irrégulier qui consomment 61% plus d’alcool à risque que les travailleurs qui ont un horaire de travail régulier. Inversement, l’insécurité d’emploi réduit de 12% le risque de faire partie du groupe de consommation d’alcool à risque, et les travailleurs bénéficiant d’un soutien social au travail courent 5% moins de risque de consommation d’alcool à risque. Pour ce qui est des médicaments psychotropes, nos analyses multiniveaux nous ont permises d’identifier deux variables des conditions de l’organisation du travail qui y sont associées de manière significative. Il s’agit de l’utilisation des compétences qui augmente de 8% le risque de faire partie du groupe de consommation de médicaments psychotropes, alors que le nombre d’heures travaillées diminue de 1% ce risque. En ce qui concerne les traits de personnalité, l’estime de soi augmente de 17% le risque de consommation d’alcool à risque, alors que le sentiment de cohésion diminue de 1% ce risque. L’estime de soi joue un rôle modérateur faible entre les conditions de l’organisation du travail et la consommation d’alcool à risque, puisque celle-ci diminue de 3% l’effet pathogène des demandes physiques imposées sur les travailleurs sur leur consommation d’alcool à risque. Pour ce qui est des médicaments psychotropes, nos résultats indiquent que l’estime de soi diminue de 4% le risque de consommation de médicaments psychotropes, le centre de contrôle interne diminue de 9% ce risque, et le sentiment de cohésion quant à lui, diminue ce risque de 3%. D’ailleurs, aucun trait de personnalité ne joue un rôle modérateur entre les conditions de l’organisation du travail et la consommation de médicaments psychotropes.

Capacidad aeróbica de bomberos aeronáuticos

Los bomberos aeronáuticos son los encargados de atender todas las emergencias en los aeropuertos y sus cercanías. Estas emergencias incluyen emergencias aéreas, en tierra, eventos con materiales peligros e incendios, entre otros. Su trabajo tiene como características la realización de actividades durante periodos largos de baja intensidad y periodos cortos de alta intensidad. De acuerdo con estas características, es necesario que los bomberos aeronáuticos tengan una buena condición física. El consumo máximo de oxígeno (VO2 máx) como indicador de capacidad aeróbica resulta indispensable para conocer el desempeño de los bomberos en su trabajo. El objetivo de este estudio es determinar la capacidad aeróbica de los bomberos aeronáuticos y sus factores determinantes. Por tanto se desarrolló un estudio transversal de tipo descriptivo en una muestra de 23 hombres bomberos aeronáuticos. Se obtuvo información acerca de sus variables socio-demográficas, se determinó el VO2 máx y umbral ventilatorio mediante análisis de gases espirados durante un protocolo de ejercicio máximo sobre tapiz rodante, se evaluó la composición corporal mediante adipometría y se determinó el nivel de actividad física mediante el cuestionario internacional de actividad física IPAQ. Se encontró que la muestra tenia una edad de 32,6 ± 4,8 años, peso de 78,4 ± 9,8 kg, porcentaje de grasa de 14,8 ± 3,8 %, índice de masa corporal de 25,7 ± 2,7 y VO2máx de 44,6 ± 6. No se encontraron cambios significativos del VO2máx con la edad, pero si con la actividad física, porcentaje de grasa e índice de masa corporal. Se sugiere que el entrenamiento de los bomberos aeronáuticos durante su jornada laboral sea de intervalos de alta intensidad y que se monitorice su nivel de actividad física y composición corporal.

Efecto de una intervención sobre la carga física durante el proceso de coquización en una empresa de Colombia

Se realizó estudio cuasi experimental con el fin de comparar el efecto sobre la carga física de una intervención tecnológica y en la organización del trabajo en trabajadores en el cargo de horneros en la tarea de extracción de coque en Colombia. Se midió la carga física mediante frecuencia cardiaca e índice de costo cardiaco relativo en una población de trabajadores expuestos (37) y no expuestos (66) a una intervención tecnológica. La monitorización de la frecuencia cardiaca se realizó con 7 pulsímetros Polar RS 800cx debidamente calibrados. Las variables numéricas se describieron con base en la media aritmética, su desviación estándar, y el rango. Para evaluar la diferencia entre las medias de los grupos con respecto a la frecuencia cardiaca en reposo, media, máxima, índice de costo cardiaco relativo, gasto energético de trabajo se aplicó análisis de varianza de una vía. Se estableció a priori un nivel de significación estadística α = 0,05. Se encontraron diferencias estadísticamente significativas en el comportamiento de la frecuencia cardiaca media, frecuencia cardiaca máxima e índice de costo cardiaco relativo, entre los grupos de estudio. Se concluyó que este estudio valida la frecuencia cardiaca como una variable sensible para la medición del riesgo por carga física y a su utilidad en la evaluación intervenciones ergonómica. El estudio demostró que la intervención ergonómica logró controlar la carga física con una disminución significativa la frecuencia cardiaca, en el grupo de intervención.

Constrangimentos no posto do motorista de ônibus urbano segundo a visão macroergonômica

Este estudo trata da abordagem macroergonômica participativa para a identificação das demandas ergonômicas dos motoristas de ônibus urbano da cidade de Joinville, com utilização da metodologia participativa da Análise Macroergonômica do Trabalho (AMT) (GUIMARÃES, 2001c) e ferramental proposto no Design Macroergonômico (DM) (FOGLIATTO E GUIMARÃES, 1999). O estudo de caso foi realizado em uma empresa privada de transporte coletivo da cidade de Joinville. A aplicação da metodologia permitiu identificar as demandas ergonômicas prioritárias levantadas pelos motoristas de ônibus urbano da cidade de Joinville e os itens de design do seu posto de trabalho através da fase de apreciação. As demandas ergonômicas, bem como os itens de design foram comparados através do Teste Exato de Fisher com determinadas características da população constatando-se algumas associações significativas entre a satisfação dos motoristas e as variáveis que compõe cada construto. Estes resultados possibilitaram a formulação de recomendações que viabilize, em estudos futuros, a introdução de melhorias para o aumento da qualidade de vida dos motoristas. Os estudos também permitiram identificar uma afinidade da metodologia participativa com os motoristas de ônibus urbano, em que as mudanças podem ocorrer de forma gradativa e experiencial através de protótipos no caso das demandas referentes à posto de trabalho e físico ambiental, ou através de possíveis adaptações no conteúdo da tarefa do motorista no caso das demandas referentes à organização do trabalho. Tudo isto vislumbrando o atendimento, por ordem de importância, dos itens de demanda ergonômica levantados. Por fim, concluiu-se que para os motoristas de Joinville alguns fatores referentes a organização do trabalho estão entre os principais causadores dos constrangimentos aos quais são expostos enquanto executam sua tarefa, seguido por fatores físicos ambientais e posto do trabalho.
